THOMAS NATHAN RUSSELL, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO CLEVELAND CAR ROOFING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CAR-ROOF.

Specification of Letters Patent.

Application filed July 21, 1913. Serial No. 780.358.

To all whom it may concern:

Be it known that I, THOMAS NATHAN Rus- SELL, a citizen of the United States, and a resident of Chicago, in the State of Illinois, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification.

My present invention relates in general to roofs and more particularly to roofs of railway cars, and has special reference to the provision of an improved form of metal roof.

The principal objects of my present invention are the provision of a roof wherein a single thickness of metal may be employed in lieu of the customary metal sheeting and wooden sheathing; the provision of an improved structure of the character referred to wherein the carlines may be employed not only for transverse support of the roof but also to cover the joints in the sheaths employed in forming the roof; the provision of an improved arrangement of metal purlins, carlines, and sheets may be employed in the production of a roof of great lightness and strength at a very low cost, and without sacrifice of rigidity, tightness, or durability; the provision of improved means for supporting the customary wooden walk or running board from a metal roof; the provision of improved means for readily attaining secure attachment of a metal roof to a car body; together with such other objects as may hereinafter appear.

In attaining the foregoing objects, together with certain additional advantages to be below disclosed, I have provided a construction, a preferred embodiment of which is illustrated in the accompanying drawings wherein Figures 1 and 2 are respectively a transverse sectional view and longitudinal elevational view of a portion of a railway box car having my improved roof applied thereto; Figs. 3' and 4 are enlarged elevational and plan views of the details of the means for attaching the roof to the car body; Fig. 5 is a sectional view illustrative of means employed for closing the joints between the plates; Fig. 6 is a sectional View illustrative of means for holding the carlines and purlins in predetermined relation with the plates in assembled position therebetween extend longitudinally of the car,

such purlins being conveniently formed of metal given semi-circular cross section and oppositely disposed flanges 15-15 for supporting the carlines 16 extending transversely of the roof. Figs. 5 and 6 are preferably of an inverted U-form having oppositely disposed laterally extending flanges 17 and are arranged to cover the joints between the adjacent sheets These carlines (see 18 as is clearly to be seen on inspection of Fig. 5.

Referring more particularly to Figs. 5 and 6, it will be observed that the sides 19 of the carline members 16 and the flanges thereof 1717 and the flanged margins 20 of the sheets 18 are complementarily formed, and that I employ intermediate filler blocks 21 for holdin the vertical portions 19 and 20 in apposition.

For the purpose of securing the carlines 16 and purlins 12 in predetermined relation, with the sheets 18 firmly fixed therebetween, the flanges 1515 of purlins, the up per portions 22 of the carlines and the blocks 21 are provided with coincident apertures, (as is clearly to be seen on inspection of Figs. 2 and 6,) for thereception of suitable connecting members such as the rivets 23.

Again referring to Fig. 6 it will be observed that in constructing my improved roof, 1 preferably employ a form of rivet having a shank '24 provided with a collar 25, for the reception of which the blocks 21 are suitably countersunk, one end of the rivet being provided with an extended portion 26 passing through the carline 16 whereby a head 27 may be formed, holding the carline in position over the margins of the adjacent sheets 18, the opposite end of the rivet which passes through the purlin being threaded for the reception of a nut 28 whereby the several members l2, l6, and 18 may be drawn closely together.

As will be apparent on inspection of the 5 drawings, the construction just described permits ready removal and replacement of any carline, purlin or sheet which may have become injured or proved defective in service, and this without undue disturbance of adjacent structural members.

Referring now more particularly to Figs. 3, 4L. and 8 it will be seen that for the purpose of attaching the roof structure to the car framing. 1 preferably provide adjacent 5 eachend of each carline 16 a combined filler-block and bolt-anchor 30 which comprises a horizontal body portion 31 apertured at 32-32 for the passage of rivets 3333 wherebv it may beattached to the portion 22 of the carline, a depending por- 34: adapted to bear against the plate member 10 and apertured at 40 for the passage of the bolt 41, a transverse portion 35, parallel stiffening webs 36-36 connecting the portions 34 and 35, and an enlarged extension 36 provided with a socket 37 for the reception of the head 38 of the bolt 39.

7 Each end of each carline 16 is closed by a combined filler block and bearing plate 42 0 comprising a body portion 43, having a depending flange l-l bearing on the fascia board 48, the body and flange being apertured for the passage of the bolts 39 and 41, as respectively indicated at 45 and 47, whereby the roof structure may be attached to plate 10.

For the purpose of supporting the running board or roof walk 50, I preferably employ a transverse commercial angle member 51 apertured as at 52 for the reception of suitable bolts 5.), the member 51 being supported at each end by a short piece of similar material such as is indicated at 54, the pieces 54: being riveted .to the member 51 5 and to the carline 16 as shown at 56 and 57 respectively. 7

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:

l. A roof comprising, in combination, roofing sheets having upturned margins, exterior carlines of inverted U-shape covering the joints between said sheets, purlins, filler blocks at the point of crossing of the carlines and purlins, and through members for securing together said carlines, filler blocks and purlins riveted to the webs of the carlines.

2. In a car roof, in combination with a plate and a carline of inverted U-shaped 0 cross section, a pair of filler blocks having depending portions adapted to bear against opposite sides of the plate and means for clamping together said filler blocks and said depending portions.

3. In a car roof, in combination with a plate and a carline, a device for attaching the carline to the plate, comprising a body adapted to be secured to the carline, said body having a depending portion adapted to bear against the plate and a socket for a bolt head, a block adjacent the end of the carline provided with a depending portion parallel to the depending portion of said body, a bolt having a head disposed in said socket and engaging said block, and a sec- 0nd bolt engaging said depending portions for securing them together with the plate therebetween.

4. In a car roof, in combination with a plate and a carline, a device for attaching the carline to the plate, comprising a body adapted to be secured to the carline, said body having a depending portion adapted to bear against the plate and a socket for a bolt head, block adjacenttne end of the carline provided with a depending portion parallel to the depending portion of said body, a bolt having a head disposed in said socket and engaging said block, and means for engaging said depending portionsfor securing them together with the plate therebetween.

5. A pitched carline having a substantially horizontal, transverse web surface and separate spaced members secured thercto on opposite sides of the ridge-line providing vertical faces, in combination with a running board saddle having a vertical face adapted to bear against said face of the members, and means for securing it thereto.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
